with@ therme-Stat if it lis desired@ cot'rl vv90 around its sides and are secured to the wall I of the chamber by means of outbent edges seen in Figure 3 at 4l. These edges engage the groove members 42 which are secured to the lire chamber wall and extend vertically thereon along the sides of the coil chamber.

Returning the description to Figure l; it will 'be seen that the element 40 which is the lower of the sheath members, is perforated as seen at 44. These perforations permit the flame from the auxiliary burner to flare out at the sides and come into contact with such material as is in the fire chamber; the flames thus pass between the pipe coils as Well as along their inner sides.

The upper element 39 of the sheath members which rests on the top of the member 4U coming in contact therewith at the point 43, has no perforations and it thus serves to keep any waste material from lodging below or about the burner nozzle and shutting od the flame from the said burner, or the pilot light. It will be observed that the flame from the said pilot light shoots across t-o the edge of the burner through the hole 45 in the lire chamber wall.

A cover plate 46 rests upon the top of the .element 89 and eects a closure over the agitating, the said waste material may be separated and moved about to permit of the flames which shoot out of the sides of the coil chamber to enter the mass; and at the same time the oxygen supply to the burning material is increased by this movement. This bar, which is seen best in Figure 2 has a cross pin 52 which is adapted to engage the plate 53 and thus acts as a stop element. An elongated slot 54 in the wall of the tire chamber permits of a Vertical swing of the bar and of forward and backward thrusts of the same, but prevents any side motion thereof. It is desirable to prevent any side play of this member as it might, if brought into violent Contact with the coil sheathing while the same was red hot, caused injury to the pipe coil. Normally, the bar is withdrawn from lthe tire chamber and hung conveniently near to the incinerator. A cover tab 55 closes the slot when the bar is removed.

Material is put into the incinerator through the chute 58 and this is covered by the lid 59. An elliptical smoke pipe 60 provides means for connection with a suitable chimney.

While the invention is shown and described in its preferred form, it is understood that it is not limited narrowly to the exact details of form and construction as herein described, but it is to be broadly construed within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is as follows:

l. In an incinerator, an outer casing, a fire chamber within the said casing, a water coil within the said chamber and having inlet and outlet connections with the exterior of the -f casing, an auxiliary fuel burner inserted within the said coil and downwardly directed and adapted to direct its flame along the interior of the coil contour, a sheathing about the upper portionof the said coil and a cover element which shuts off the area adjacent the nozzle of the said burner from the tire chamber, and a lower sheathing about the said coil, which sheathing is provided with openings adapted to allow the passage of the aux-v iliary burner flame from the inner area of the coil to the interior of the said fire chamber.

2. An incinerator of the class described comprising, an outer casing, an interior fire chamber, a water coil placed within the said chamber and having inlet and outlet connections, the said coil being parted at one side for the passage of an auxiliary burner which is downwardly directed, and the said coil wound below the said burner in a series of turns which are separated from each other and permit of the passage of a portion of the flame from the said burner to the lire chamber, means to ensheath the said water coil and means for the passage of flames from the said auxiliary burner through the said sheathing.

3. In an incinerator, an outer casing, a tire v chamber within the said casing, a water coil v supported vertically within the said fire chamber and the said coil having its lower convolutions spread apart, and its upper coils widely parted at the back for the passage of an auxiliary burner between the same, the said burner being downwardly directed within the coil convolutions, a close walled sheathing about the upper portion of the said coil and a perforated sheathing about the lower portion thereof, an inclined cover plate over the said coil and sheathing, and inlet and outlet extremities of the said coil passing through the outer casing and inclosed within sleeve members which also act as partial supports for the lire chamber.

4. In an incinerator having a fire chamber consisting of a perforated wall set in spaced relation to an outer easing, a water Coil set within the said re chamber and at one side thereof, and the said coil encased around its upper portion with a closed sheathing, and around its lower portions with a perforated sheathing, and a cover element over the top of the said closed sheathing, and an auxiliary burner inserted within the contours of the said coil and set to direct its flames in a downward course within the convolutions of the said coil.
